Front-Mounted Manure Transfer Layout for Balanced Axle Load

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing transfer devices for liquid manure between containers on agricultural spreading vehicles suffer from uneven weight distribution due to the weight of the wet shredder and heavy material separator acting on the rear hitch, necessitating additional front weights for balance.

Innovation Solution

The transfer device is designed with a front-mounted coupling that includes a wet shredder and heavy material separator, distributing the weight onto the front axle of the vehicle, eliminating the need for additional front weights and optimizing the flow path for liquid manure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wet shredder with heavy material separator is located on the rear container, then the transfer function between containers is achieved, but the weight distribution becomes unbalanced with excessive load on the rear axle

Engineering Contradiction:

Improvetransfer functionVSAvoidweight distribution

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The patent inverts the conventional location of the wet shredder from the rear container to the front container. This inversion changes the weight distribution from rear-heavy to front-balanced, eliminating the need for additional front weights while maintaining the transfer function between containers.

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If additional front weight is attached to balance the vehicle, then weight distribution improves, but device complexity increases

Engineering Contradiction:

Improveweight distributionVSAvoiddevice complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts the wet shredder from its conventional location and relocates it to the front container. This extraction eliminates the need for separate front weight attachments, reducing device complexity while maintaining proper weight distribution.

Inventive Principle:

Principle #2Taking out (Extraction)

3Weight of moving object

If the wet shredder is relocated to the front container, then weight distribution improves, but the flow path for liquid manure becomes longer

Engineering Contradiction:

Improveweight distributionVSAvoidflow path

Core Design Contradiction:

Weight of moving objectVSLength of moving object

Solution Approach 1:

The patent utilizes the vertical dimension by positioning the inlet opening at the top of the front container and the outlet at the bottom, creating a vertical flow path that compensates for the horizontal relocation of the wet shredder. This dimensional approach maintains efficient fluid flow despite the changed configuration.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
